| Calculate the standard error of the sample proportion. (Round your answers to 4 decimal places.) |
| Standard Error | |
| (a) n = 30, ? = 0.50 | |
| (b) n = 50, ? = 0.20 | |
| (c) n = 100, ? = 0.10 | |
| (d) n = 500, ? = 0.005 |
| Calculate the standard error of the sample proportion. (Round your answers to 4 decimal places.) |
Solution
(a) Standard Error= sqrt(p*(1-p)/n) = sqrt(0.5*0.5/30) = 0.0913
(b) Standard Error =sqrt(0.2*0.8/50) = 0.0566
(c) Standard Error=sqrt(0.1*0.9/100) = 0.0300
(d) Standard Error =sqrt(0.005*0.995/500) = 0.0032
